  1. …from it, to a lesser degree. There are important HLSL intrinsics that are vendor-dependent ( https://github.com/Microsoft/DirectXShaderCompiler/wiki/Wave... or https://github.com/NVIDIA/nvapi/blob/main/nvHLSLExtns.h ). Microsoft used to be…

  2. The Microsoft HLSL compiler for dx12+ is based on LLVM and supports spir-v output https://github.com/microsoft/DirectXShaderCompiler Though my understanding is that it's a complete hackjob stuck on an old version of LLVM, and not in a…

  3. On the latest release https://github.com/microsoft/DirectXShaderCompiler/releases/... There are "source code" files in zip and tar.gz Aren't those source code for those dlls?

  4. Which part of dxil/dxc is proprietary exactly? Trying to make sense of the license barf at https://github.com/microsoft/DirectXShaderCompiler

  5. No, it's C++, based on LLVM. https://github.com/microsoft/DirectXShaderCompiler Edit: apparently dxil.dll is not part of DXC (the classic move to make "open source" software dependent on external proprietary garbage, apparently.) But I'd…

  7. Well... they are rewriting & upstreaming DXC to LLVM main ( https://github.com/microsoft/DirectXShaderCompiler/wiki/Cont... ) and want to kinda deprecate DXC. IIRC currently only compute shaders are supported but I may be very wrong.

  8. There's no need for transpilers these days, you can just compile HLSL to SPIR-V bytecode with dxc. https://github.com/microsoft/DirectXShaderCompiler
